thanks for the reply.
so besides the controller, are there any other change? sensor,pump, etc?
It is not that simple, the Osmolator, like most of our products see some minor tweak or upgrade about every 6 months, so it is more of an evolution than an abrupt change. The pumps have always been the same, over the last 10 years there have been 4 distinct sensors, the changes are subtle and geared toward balancing sensitivity to water level change to susceptibility to errors from bubbles and reflection. This is fairly typical of German engineering, the VW beetle had a production run of more than 50 years, outwardly they look very similar but from the first car to the last, there was only one gasket that was identical. There are constant small changes to board components as well, a capacitor for example will change if one is found to be better than what we were using, we just changed the female power receptacle to a nicer more flush appearance one that is better sealed against salt creep and humidity. Between the two you show, if one was from say Aug 2010 (old style) and the new one was Sept 2010 (new style) the only difference would be the housing and shorter LED legs to fit under the housing. But between today and June 2002 it would be a night and day difference, not a single piece would be the same, the oldest one would be a fairly primitive, entirely hand soldered board, the latest one would have a new board that is firmware based and surface mount. The sensor would be different, the pump connector clips would be different, the power supply would be different.
